My process won't start using systemctl but starts using commandLine

Hi @Jose_Felipe_Goncalves_Rocha,
Why only 2 servers?
Dumb question, is the generated keyfile the same for both servers?
In case the answer is yes, could you try to regenerate it maybe from server 2 or server 1 and redistribute it?

I personally prefer to create a replica set with 3 nodes that have the same os and characteristics for convenience.

Regards
